`baseclassname::f()' calls the function `f' declared in `baseclassname' or
one of its base classes. The call is checked for ambiguity of `f' in
`baseclassname'.

As noted, the most common use of this is to call a function f() from a
base class from a function f() in a derived class.


This was always so. It will remain so. I will make sure that the reference
manual is precise and explicit about this.

I guess that the most obvious facts are also the easierst ones to forget to
mention. Sorry.

The `inherited::f()' idea works only for single inheritance - that was why is
wasn't used. It seems that this notation can be added to C++ with multiple
inheritance without much trouble but that does not in itself prove that it
ought to be added. We'll see.
